Wireless auto configuration dynamically selects the wireless network to which to attempt connection. Stand-alone wireless networks utilize the lower layer networks to provide those features. Recently, a stronger security protocol allows a person to set up to a 128-bit security key that is shared between a mobile device and its access point. Wireless networks are rapidly becoming a cost-effective alternative for providing network connectivity for banking information systems. Wireless networks provide their own physical layer networks, utilizing antennas built into handheld devices to large antennas mounted on towers. Wireless networks are more challenging to manage than wired networks because they require more network nodes, device types, network types, and network layers.
